They all loved each other like no one else would care for their siblings. They laughed, killed and fought all their problems together. How would they deal with a new member in the family when their only sister (Y/N) is uncomfortable around her.

Y/n is a part of the BTS. Only girl member. Y/n is quite introvert, doesn't talk to anybody more than its needed. Y/n is very particular towards respecting the other members of the group. She is the youngest one yet most responsible and takes care of her group members very well. Y/n falls in love with an very famous actor but she scared to tell her band members. Other BTS members are her brothers. She is supposed to call them Oppa but instead she calls them Hyung. Look forward to the Fiction.
